What is maca powder?

Maca is a plant that is also known as Peru ginseng. Strictly speaking, maca is a tuber and belongs to the cruciferous family. The tuber is used for its effects such as lowering blood pressure and reducing inflammation. The Incas used it to increase concentration and strength.

The taste of the tuber is very intense and is described as earthy, nutty and with a light caramel aroma.

In addition, many athletes use Maca to support muscle regeneration. Maca has 325 calories per 100 grams. This content can be compared to that of a normal potato. However, the protein content is significantly higher, which makes the root very interesting for athletes.

Where does maca powder originally come from?

Maca originally comes from Peru. There it grows in the Andes and at an altitude of over 4000 meters. At these altitudes, the tuber has to withstand very harsh weather conditions. These range from high UV radiation and strong winds to rapid temperature fluctuations.

The plant grows up to 20 centimeters in height. However, this part of the plant is only ornamental, since the effect of the plant arises from the root. The Incas incorporated maca into their cuisine as an essential food. Maca can be enjoyed in the form of porridge, sauces or baked as a whole tuber.

How is maca powder obtained?

Maca powder is an extract obtained from the maca root. After the roots have been harvested, they are spread out on tarpaulins next to the fields to dry. After about 10 days, the dried tubers are weighed and packaged.

The packaged tubers are taken to production facilities for further processing. There they are sun-dried again. After the tubers have undergone a final UV drying process, they are washed and disinfected for further processing. In the last step, the roots are crushed in a grinding machine and the tubers are processed into granules. After a final check, the product is then delivered.

What types of maca powder are there?

The maca root is divided into four different varieties. The first type is yellow maca, the second is red maca, the third is purple maca and the last type is black maca. The different varieties of the root have individual effects and can be consumed individually or mixed as mixed maca, depending on requirements.

How to dose maca powder for the right effect?

The dosage of Maca powder depends on the desired effect. For example, if you take the powder during menopause, 2 to 3.5 grams should be enough. In a depressed mood, a dose of 0.5 to 3 grams is ideal.

If the powder is consumed for regeneration and in combination with sport, then an amount of 2 to 3 grams is recommended. 3-4 grams of maca powder per day is a recommended dosage. In principle, however, a dosage of more than 6 grams per day should be avoided.

Otherwise, it can lead to stomach pain, bloating, indigestion, hyperactivity and headaches. Nevertheless, maca has no toxic effect on the human body and can be consumed in large quantities without any damage to health.

  • Maca Yellow
  • Maca Red

  • Maca Black

The different types of Maca have different effects on the consumer depending on gender. Yellow Maca helps, for example, during postmenopause but also generally as a mood enhancer. Red Maca prevents prostate enlargement and can also improve the chances of conception.

Violet Maca can be used mainly during the premenopause.

Black Maca is especially good for men. A higher sperm count, improved libido and more testosterone is possible. In general, taking it is also useful for improving mental clarity.

However, it is very important to underline that these effects are not all proven. Some of the effects are attributed to the plant or shaped by the importers of the product in such a way that they no longer have much to do with the statements made by the farmers living in Peru.

What do studies and science say about the effects of maca powder?

Science is divided on the effects of Maca. There are some effects that have been proven, while other effects have not been scientifically proven.

All of this took place over a period of 6 weeks. The results were no differences in terms of hormones between the test groups. Nevertheless, the blood pressure in the Maca group was significantly reduced, as was the level of depression.

Another study tested the effect of maca on sexual behavior in men between the ages of 21 and 56. The subjects received a daily dose of 1.5 grams, 3 grams or a placebo. The period was 12 weeks and regular interim tests were carried out. After just 8 weeks, an increased sex drive was noticed. However, testosterone levels in the placebo group were the same as the normal group.

Is Maca Powder Harmful?
